. Patented-Dec. S, 1914.

Application filed May 14, 1914. Serial No. 832,524.

To all whom it may concern Be it known that 1, JOHN W. FORGE, a citizenof the United States, residing at New Britain, in the county of Hartfordand State of Connecticut, have invented certain new and usefulImprovements in Turn-Buttons, of which the following is a specification.

Fly invention relates to improvements in turn buttons, of the type usedfor automobile curtains, and the object of my'improvement is simplicityand economy in construction and convenience and efliciency in use.

In the accompanying drawing, Figure 1 is a side elevation of my improvedturn button. Fig. 2 is a plan view of the same. Fig. 3 is a similar viewof the same, with the head turned 90 degrees from the position shown inFig. 2. Fig. 4 is a side elevation of the same. Fig. 5 is a sectionalview on an enlarged scale on the line w m of Fig. 2. Fig. 6 is a planview of the base. Fig. 7 is a side elevation of the head. Fig. 8 is abottom view of the same;

My improved turn button comprises a base 10 on which is rotativelymounted the head 11. The base 10 comprises a shell-like structure havingan oval formation for the body portion, provided at the lower end with aflanged base portion 12 and closed at the upper end by a platform 14,which latter has a hole 15 for the pivotal pin 16. The pivotal pin 16 isconnected at the upper end to the head 11, extends downwardly throughthe hole 15, has the lower end 21 headed, and has mounted on its bodyportion a washer 22 resting on the headed lower end 21 and a spring 23,whereby the head 11 is operatively held in resilient engagement with thebase 10.

Looking means are provided for locking the head 11 relatively to thebase 10 in one or the other of the alternative positions to which it maybe set, and shown in Figs. 2 and 3 of the drawings, in the followingmanner: The bottom portion of the head 10 is of the same size and shapeas the platform 14, both being oval, and they each comprise a centralportion, surrounding the hole 15 and the pin 16, which are always inengagement or in opposition, and end portions 25, one on each side ofthe central portion, and which are in engagement in one position, asshown in Fig. 2, the one covering the other, and which are disengagedand uncovered in the other position, as shown in Fig. 3, tions of thehead 11 overhanging the lateral wall of the base 10. The central portion26 of the base 10 is dished to provide a concavity of hemi-sphericalform, extending appreciably downwardly below the platform 14, and on theface of the wall of the said concavity 26 there is a plurality ofupwardly extending ribs 27, having a rounded or V shaped cross-section.I The central portion of the head 11 is formed as the counterpart of theconstruction described, comprising downward extension 28 of the bodyportion of hemi-spherical form and which is provided with a plurality ofgrooves 29 corresponding in number to the ribs 27 and of suitable formto receive and house the same. As shown there are four ribs 27 andgrooves 29, arranged in pairs in diametral planes, the plane of one pairbeing at right angles to the plane of the other. The ribs and grooveswhen engaged serve to lock the head 11 relatively to the base 10 in oneor the other of the alternative positions, the one being at right anglesto the other. The depressed portion or concavity 26 is made of slightlysmaller diameter than the width of the base 10, so that a face to facecontact of the platform 14 and the head is always insured when in eitherposition in use, thus preventing the admission of moisture to theinterior of the base and to the spring.

The provision of a plurality of locking members, or a number greaterthan the usual pair as ordinarily found in devices of the kind describedinsures a superior and more positive locking of the parts and the curvedoutline of the locking members serves to insure the engagement of, thesame in proper manner when moved from one ofthe positions of engagement,avoiding becoming set at a position intermediate to one of the lockingpositions. F urthermore, owing to the close joint of the platform andhead the outside finish to the button and head, which in some casesconsists of a spraying with japan, may be applied to the same with theparts completely assembled and in condition for use. The provision offour ribs as shown also insures a longer life of the parts in use.Furthermore, the dished portion 26 of the base 10 and the downwardextension 28 of the head 11 serve as cooperating positioning memandexposed, theend por a depressed portion on one of the said members andan extension on the other or the said members fitting the said depressedportion, and a set of cooperating ribs and grooves on the said depressedportion and hers for positioning the head 11 on the platform 1 k of thebase 10, as will be noted from the sectional View shown in Fig. 5, so asto effect a locking of the same against relative 5 sliding movement.
